Create Feature Branch

Create and switch to a new git feature branch for the given specification. This command handles branch creation only — the spec directory and files are created by the core /speckit-specify workflow.

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Environment Variable Override

If the user explicitly provided GIT_BRANCH_NAME (e.g., via environment variable, argument, or in their request), pass it through to the script by setting the GIT_BRANCH_NAME environment variable before invoking the script. When GIT_BRANCH_NAME is set:

• The script uses the exact value as the branch name, bypassing all prefix/suffix generation
• --short-name, --number, and --timestamp flags are ignored
• FEATURE_NUM is extracted from the name if it starts with a numeric prefix, otherwise set to the full branch name
